Aramis, a 10-month-old Beagle, was described as “twitching and unable to stand” when he chewed on a packet which contained a powered substance.

His owners, who have not been named, said he immediately became unwell and they rushed him from the beach at St Cyrus village in Aberdeenshire to the nearby Robson Veterinary Hospital in Laurencekirk.

Aramis has now made a full recovery after the incident on Saturday afternoon.

But vet Ian Anderson said: “The dog was showing signs of stimulation to the nerves. He was twitching and turning and not able to walk or stand and also had a very fast heart rate. I suppose in straight forward terms, it was spaced out.

“It was quite frightening for the owners of the dog. They took it away form him and realised the packet contained one of these products called legal highs and then by the time they left the beach the dog was starting to show clear signs of intoxication from it.”
